Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, in particular to a switchable double-tube filter. Background Art

[0002] An oil filter is a device used to filter impurities from oil. It is commonly used in engines, hydraulic systems and other mechanical equipment. Its main function is to capture and isolate particles, dirt, moisture and other contaminants in the oil to ensure smooth and effective operation of the system and extend the service life of the equipment. A switchable duplex filter is a filter structure with two filter cartridges designed to improve the continuous operation capability of the system. Its working principle is to use two filter cartridges to filter the oil in turn, ensuring that when one filter cartridge needs to be cleaned or replaced, the other filter cartridge can still continue to work, so as not to affect the operation of the entire system.

[0003] In the prior art, during the use of the switchable double-barrel filter, when the filter element in the filter cartridge filters impurities in the oil, some of the oil will adhere to the impurities and the filter element. When the filter element needs to be taken out to clean the impurities and garbage, some of the oil attached to the impurities and the filter element will also be brought out of the filter cartridge. The brought out oil is not only easy to drip onto the ground or the work area, causing oil pollution, increasing the subsequent cleaning workload and cleaning difficulty, but also causing a waste of this part of the oil resources and increasing operating costs.

[0004] Therefore, we propose a switchable double-tube filter to solve the problems raised in the above background technology. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the present invention is used, the pressing plate and the movable rod are pushed downward, so that the pressing ring pushes the fixed plate and the fixed rod to move downward, and the conical block generates thrust on the adjusting ring, driving the connecting plate and the clamping rod to move and leave the clamping groove, so that the arc spring sheet rebounds and the rubber pad returns to its original state and does not contact the inner wall of the filter housing. Start the servo motor to drive the rotating shaft and the gear to rotate, and further drive the inner gear ring, the fixed plate and the fixed rod to rotate, thereby driving the fixed ring and the filter cartridge body to rotate rapidly, generating centrifugal force, and throwing the attached oil onto the inner wall of the filter housing and flowing downward. Open the control valve in advance, and recycle it through the outlet pipe to the outside, so as to separate the oil attached to the filter cartridge body and reduce oil adhesion. Under the action of the oil removal component, the effect of separating the oil is achieved, reducing the waste of residual oil and avoiding oil pollution on the ground or working area.

[0020] 2. When the present invention is used, the connecting ring is pulled upward, and the annular pull plate is driven to move upward through the limit rod, generating an upward pulling force on the arc spring sheet and the rubber pad, forcing them to be flattened and protruding outward, pushing the rubber pad outward, and tightly contacting the inner wall of the filter housing. At the same time, the slot moves to the position of the card rod, and under the rebound of the reset spring, one end of the card rod is inserted into the slot, and the moved limit rod is limited, so that the fixed ring and the filter housing are closely connected to prevent the subsequent oil filtration from affecting the purity of the oil without being filtered by the filter cartridge body. After the arc spring sheet and the rubber pad are restored to their original state, they do not contact the inner wall of the filter housing, and do not affect the subsequent treatment of the residual oil in the oil removal assembly. When the filter cartridge body is subsequently removed from the inside of the filter housing, it can prevent the fixed ring from contacting the inner wall of the filter housing too closely, causing the oil attached to the inner wall of the filter housing to be scraped off and flow to the outer surface of the equipment, causing the equipment to be dirty.

[0021] 3. When the present invention is used, the oil inlet switching valve and the oil outlet switching valve are used to control the oil inlet channel and the oil outlet channel, so that the oil enters one of the oil discharge pipes through the oil inlet switching valve, and then enters the filter cartridge body through the fixing ring for oil filtration. The filtered oil is discharged through the oil outlet pipe and the oil outlet switching valve. Without affecting the oil filtration, the filter cartridge body in the other filter housing can be subjected to oil separation treatment. With the cooperation of the oil removal component and the sealing component, the oil filtration and impurity cleaning operations can be achieved simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom ends of the two groups of movable rods 215 are fixedly installed with pressing rings 216, and the tops of the two groups of movable rods 215 are fixedly installed with pressing plates 217. Seven first sealing holes 218 are provided at the tops of the two fixed rings 202 near the inner walls, and seven second sealing holes 219 are provided at the tops of the two fixed rings 202 near the outer surfaces. The inner walls of the multiple first sealing holes 218 are fixedly connected with first sealing rings 220, and the inner walls of the multiple second sealing holes 219 are fixedly connected with second sealing rings 221. The bottom surfaces inside the two filter housings 103 are fixed A bottom ring 222 is installed, and a plurality of hollow ball covers 223 are fixedly installed on the top of the two bottom rings 222, and balls 224 are movably embedded in the interior of the plurality of hollow ball covers 223. A sealing port 112 is opened at the center of the top of the two sealing covers 104, and the outer surfaces of the two sealing members 212 are respectively fixedly installed on the inner walls of the two sealing ports 112. The outer surfaces of the two gears 213 are respectively meshed with the insides of the two inner gear rings 208. Two pressing rings 216 are respectively movably sleeved on the outer surfaces of the two rotating shafts 211, and the bottoms of the two pressing rings 216 are respectively in contact with the auxiliary rods. Two pressing plates 217 are respectively movably sleeved on the outer surfaces of the two rotating shafts 211, and the outer surfaces of the plurality of fixed rods 204 are respectively in contact with the inner walls of the plurality of first sealing rings 220.The multiple balls 224 are evenly divided into two groups. The bottoms of the two filter cartridge bodies 201 are in contact with the outer surfaces of the two groups of balls 224. The outer surfaces of the two filter cartridge bodies 201 and the two fixing rings 202 are respectively movably embedded in the interior of the two filter housings 103. The seven supporting springs 206 distributed on each circumference of the multiple supporting springs 206 form a group. One end of the two groups of supporting springs 206 is respectively fixedly installed on the bottom surface of the two annular grooves 203. The top ends of the two groups of fixing rods 204 are respectively movably penetrated to the tops of the two fixing rings 202. The outer surfaces of the two filter housings 103 are fixedly connected with the liquid outlet pipes 110 near the bottom. The outer surfaces of the two liquid outlet pipes 110 are both provided with control valves 111.

[0039] In this embodiment, when in use, by pushing the pressing plate 217 downward, the movable rod 215 moves downward in the movable groove 214, and pushes the pressing ring 216 to move downward, and then by pushing the auxiliary rod, the inner gear ring 208 is driven to move downward on the outer surface of the gear 213, and at the same time drives the fixing plate 207 and the fixing rod 204 to move downward, so that the conical block 205 moves downward in the adjusting ring 309, and generates a thrust on the adjusting ring 309, so that it moves toward the inner wall of the annular groove 203, and drives the connecting plate 308 to move together, thereby pulling one end of the clamping rod 307 out of the clamping groove 305. At this time, the limiting rod 304 loses its limit, and the arc spring sheet 302 rebounds to return to its original state, driving the rubber pad 303 to return to its original state and not in contact with the inner wall of the filter housing 103. Then start the servo motor 210 corresponding to the filter cartridge body 201 that needs to be cleaned of impurities, and the rotation of the output end of the servo motor 210 drives the rotating shaft 211 and the gear 213 to rotate, further drives the internal gear ring 208, the auxiliary rod and the fixed plate 207 to rotate, and then drives the multiple fixed rods 204 to rotate, thereby driving the fixed ring 202 and the filter cartridge body 201 to rotate rapidly, generating centrifugal force, and throwing the oil attached to the filter cartridge body 201 and the oil attached to the internal impurities onto the inner wall of the filter housing 103 and flowing downward. Open the control valve 111 in advance, and the oil removed by centrifugation flows to the bottom surface inside the filter housing 103, and flows out through the liquid outlet pipe 110 for recovery, thereby separating the oil attached to the filter cartridge body 201 and reducing oil attachment. Then unscrew the connecting bolts between the sealing cover 104 and the filter housing 103, pull the mounting plate 209 upward, remove the rotating shaft 211 and the gear 213 from the filter housing 103, and finally remove the fixing ring 202 and the filter cartridge body 201 to clean the impurities. Under the action of the oil removal component 2, the effect of separating the oil is achieved, the residual waste of the oil is reduced, and the oil pollution to the ground or the working area is avoided. The problem that when the switchable double-barrel filter is used, when the filter element is taken out for cleaning, part of the oil attached to the impurities and the filter element will be taken out of the filter cartridge together, and the oil taken out is not only easy to drip on the ground or the working area, causing oil pollution, increasing the subsequent cleaning workload and cleaning difficulty, but also causing waste of oil resources and increasing operating costs. When the filter cartridge body 201 rotates, it drives multiple balls 224 to rotate in the corresponding hollow ball cover 223, which is conducive to reducing the friction between the filter cartridge body 201 and the filter housing 103, and facilitates the filter cartridge body 201 to better perform centrifugal rotation and separate residual oil.

[0040] Embodiment 2: Figure 7-Figure 8 and Figure 10-13As shown, an oil removal component 2 and a sealing component 3 are arranged inside the double-barrel filter component 1, and the sealing component 3 includes two annular pull plates 301, and five arc-shaped spring sheets 302 are fixedly installed on the top of the two annular pull plates 301, and five arc-shaped spring sheets 302 distributed on each circumference of the multiple arc-shaped spring sheets 302 form a group, and rubber pads 303 are arranged on the outer surfaces of the two groups of arc-shaped spring sheets 302, and seven limit rods 304 are fixedly installed on the inner walls of the two annular pull plates 301, and the outer surfaces of the multiple limit rods 304 are provided with card grooves 305 near the bottom ends, and seven support plates 306 are fixedly installed inside the two annular grooves 203, and card rods 307 are movably embedded inside the multiple support plates 306, and connecting plates 308 are fixedly installed on one end of the multiple card rods 307, and adjusting rings 309 are fixedly installed on the outer surfaces of one side of the multiple connecting plates 308, and reset springs are movably sleeved on the outer surfaces of the multiple card rods 307 Spring 310, seven limit rods 304 distributed on each circumference of the multiple limit rods 304 form a group, and the tops of the two groups of limit rods 304 are fixedly installed with connecting rings 311, the outer surfaces of the two annular pull plates 301 are respectively movably embedded in the inside of the two annular grooves 203, the bottoms of the two rubber pads 303 are respectively fixedly connected to the tops of the two annular pull plates 301 near the edges, and the tops of the two rubber pads 303 are respectively fixedly connected to the top surfaces inside the two annular grooves 203, the outer surfaces of the multiple limit rods 304 are respectively in contact with the inner walls of the multiple second sealing rings 221, the outer surfaces of the multiple fixing rods 204 and the outer surfaces of the multiple conical blocks 205 are respectively movably embedded in the inside of the multiple adjustment rings 309, one end of the multiple reset springs 310 is respectively fixedly connected to the outer surfaces of the other side of the multiple connecting plates 308, and the other ends of the multiple reset springs 310 are respectively fixedly connected to the outer surfaces of one side of the multiple support plates 306.

[0041] In this embodiment, when in use, the other end of the clamping rod 307 contacts the limiting rod 304, and the reset spring 310 is in a stretched and expanded state. The two filter cartridge bodies 201 and the corresponding fixing rings 202 are placed inside the two filter housings 103 respectively, and fall onto the ball 224. Then, the connecting ring 311 is pulled upward to drive the multiple limiting rods 304 to move upward, and at the same time, the annular pull plate 301 moves upward in the annular groove 203, generating an upward pulling force on the arc spring sheet 302 and the rubber pad 303, forcing them to be flattened, and the arc-shaped side edges of the arc spring sheet 302 protrude outward, and push the rubber pad 303 outward, so that the rubber pad 303 is in tight contact with the inner wall of the filter housing 103. As the limiting rod 304 moves upward, the clamping groove 305 moves upward to the clamping rod 307. At this time, the clamping rod 307 and the reset spring 310 lose the limiting rod. The thrust of the return spring 310 drives the connecting plate 308 and the clamping rod 307 to move under the rebound of the return spring 310, so that one end of the clamping rod 307 is inserted into the clamping groove 305, thereby limiting the moved limiting rod 304, so that the arc spring sheet 302 and the rubber pad 303 remain in the state of being flattened and deformed, so that the fixing ring 202 and the filter housing 103 are closely connected, preventing part of the oil from accidentally flowing downward from the space between the fixing ring 202 and the inner wall of the filter housing 103 during subsequent oil filtration, without being filtered by the filter cartridge body 201, affecting the purity of the oil. At the same time, the connecting plate 308 drives the adjusting ring 309 to move together, so that the inner wall of the adjusting ring 309 contacts the outer surface of the conical block 205. Then, the sealing cover 104 and the servo motor 210 on the top are moved downward and installed to the top of the filter housing 103 by bolts, so that the gear 213 is inserted into the inner gear ring 208 and meshes with it, and at the same time, the bottom of the pressing ring 216 contacts the auxiliary rod on the outer surface of the inner gear ring 208. After the installation of the oil removal assembly 2, the sealing assembly 3 and the double-tube filter assembly 1 is completed, the oil can be filtered through the double-tube filter assembly 1. By pushing the pressing plate 217 downward, the movable rod 215 pushes the pressing ring 216 to move downward, driving the fixing plate 207 and the fixing rod 204 to move downward, so that the conical block 205 moves downward in the adjusting ring 309, generating a thrust on the adjusting ring 309, causing it to move toward the inner wall of the annular groove 203, driving the connecting plate 308 to move together, thereby pulling one end of the clamping rod 307 out of the clamping groove 305, causing the arc-shaped spring sheet 302 to rebound and return to its original state, driving the rubber pad 303 to return to its original state, and not contacting the inner wall of the filter housing 103, and not affecting the subsequent treatment of residual oil in the oil removal assembly 2. When the filter cartridge body 201 is subsequently removed from the inside of the filter housing 103, it can prevent the fixing ring 202 from contacting the inner wall of the filter housing 103 too closely, causing the oil attached to the inner wall of the filter housing 103 to be scraped off and flow to the outer surface of the equipment, causing the equipment to be dirty.

[0043] In this embodiment, when in use, the oil inlet switching valve 106 and the oil outlet switching valve 107 are used to control the oil inlet channel and the oil outlet channel, so that the oil enters one of the oil discharge pipes 108 through the oil inlet switching valve 106, and then enters the filter cartridge body 201 through the fixing ring 202 for oil filtration. The filtered oil is discharged through the oil outlet pipe 109 and the oil outlet switching valve 107. Without affecting the oil filtration, the filter cartridge body 201 in the other filter housing 103 can be subjected to oil separation treatment. With the cooperation of the oil removal component 2 and the sealing component 3, the oil filtration and impurity cleaning operations can be achieved simultaneously.

[0044] The effect and working principle of the whole mechanism are as follows: two filter cartridge bodies 201 and corresponding fixing rings 202 are placed inside two filter housings 103 respectively, and fall onto the ball bearings 224. Then the connecting ring 311 is pulled upward, driving the plurality of limit rods 304 to move upward, and at the same time driving the annular pull plate 301 to move upward in the annular groove 203, generating an upward pulling force on the arc spring sheet 302 and the rubber pad 303, forcing them to be flattened, and the arc-shaped side edge of the arc spring sheet 302 protruding outward, and pushing the rubber pad 303 outward, so that the rubber pad 303 is in tight contact with the inner wall of the filter housing 103, and as the limit rod 304 moves upward, the card slot 30 5 moves upward to the clamp rod 307. At this time, the clamp rod 307 and the return spring 310 lose the thrust of the limit rod 304. Under the rebound of the return spring 310, the connecting plate 308 and the clamp rod 307 are driven to move, so that one end of the clamp rod 307 is inserted into the inside of the clamping groove 305, thereby limiting the moved limit rod 304, so that the arc spring sheet 302 and the rubber pad 303 remain in a state of being flattened and deformed, so that the fixing ring 202 and the filter housing 103 are tightly connected. At the same time, the connecting plate 308 will drive the adjustment ring 309 to move together, so that the inner wall of the adjustment ring 309 contacts the outer surface of the conical block 205. Then the sealing cover 104 and the servo motor 210 at the top are moved downward and installed to the top of the filter housing 103 by bolts, so that the gear 213 is inserted into the inner gear ring 208 and meshes with it, completing the installation of the oil removal component 2, the sealing component 3 and the double-tube filter component 1. The oil inlet switching valve 106 and the oil outlet switching valve 107 are used to control the oil inlet channel and the oil outlet channel, so that the oil enters one of the oil drain pipes 108 through the oil inlet switching valve 106, and then enters the filter cartridge body 201 through the fixing ring 202 for oil filtration. The filtered oil is discharged through the oil outlet pipe 109 and the oil outlet switching valve 107. Without affecting the oil filtration, the filter cartridge body 201 in the other filter housing 103 can be subjected to oil separation treatment. The pressing plate 217 is pushed downward, so that the movable rod 215 moves downward in the movable groove 214, and pushes the pressing ring 216 to move downward, and then the inner gear ring 208 is driven to move downward on the outer surface of the gear 213 by pushing the auxiliary rod, and at the same time drives the fixing plate 207 and the fixing rod 204 to move downward, so that the conical block 205 moves downward in the adjusting ring 309, and generates a thrust on the adjusting ring 309, so that it moves toward the inner wall of the annular groove 203, and drives the connecting plate 308 to move together, so that one end of the clamping rod 307 is pulled out of the clamping groove 305. At this time, the limiting rod 304 loses its limit, and the arc spring sheet 302 rebounds to return to its original state, driving the rubber pad 303 to return to its original state and not in contact with the inner wall of the filter housing 103.Then start the servo motor 210 corresponding to the filter cartridge body 201 that needs to be cleaned of impurities, drive the rotating shaft 211 and the gear 213 to rotate, further drive the internal gear ring 208, the auxiliary rod and the fixed plate 207 to rotate, and then drive the multiple fixed rods 204 to rotate, thereby driving the fixed ring 202 and the filter cartridge body 201 to rotate rapidly, generating centrifugal force, and throwing the oil attached to the filter cartridge body 201 and the oil attached to the internal impurities onto the inner wall of the filter housing 103 and flowing downward. Open the control valve 111 in advance, the oil removed by centrifugation flows to the bottom surface inside the filter housing 103, and flows out through the liquid outlet pipe 110 for recovery, thereby separating the oil attached to the filter cartridge body 201 and reducing the oil attachment. Then unscrew the connecting bolts between the sealing cover 104 and the filter housing 103, pull the mounting plate 209 upward, remove the rotating shaft 211 and the gear 213 from the filter housing 103, and finally remove the fixed ring 202 and the filter cartridge body 201 to clean the impurities.
